Pavlov was born on April 2, 1933, in the former village of Vitoshko, near the capital Sofia.[1] He was among the few Bulgarian authors and intellectuals who dared to act autonomously and defy the Bulgarian Communist government, which ruled the country from 1945 until 1989.[1] Government censors began a ten-year-long publishing ban against his work beginning in 1966.[1] Bulgarians began illegally publishing and reading Pavlov's poems during the censorship against his work.[1]

Some of Pavlov's most popular works of poetry included Sweet Agony, published in 1991; The Murder of the Sleeping Man in 1992; and the A Long Time Ago ... in 1998.[1]

Konstantin Pavlov died in Sofia, on September 28, 2008, at the age of 75.[1] He was survived by his wife, Maria, and their daughter, Donka.[1] His death was announced by the Union of Bulgarian Film Makers.[1]
